Material Categories
Material families described by composition, typical use and documented limits, so a category can be judged before individual products are compared.

Recycled PU leather
A synthetic sheet with recycled input, often outperforming plant-input alternatives on abrasion and wet-rub while carrying a substantiable recycled percentage. The risk here is the wording, not the material: sold as 'eco leather', it…

Cork leather
One of the few categories where the plant portion really is most of the material — the backing textile is the synthetic part, and an FSC claim covers the cork, not the backing. Surfaces…

Recycled plastic components
Recycled polymer varies more between lots than virgin material, and small mouldings are where that variance shows first, as brittleness. Ask for the recycled percentage and the lot test; a supplier who can produce…

Recycled metal hardware
Often the heaviest component by weight and the one routinely left out of a brand's material claim. Recycled content in metal is well established and cheap to verify, so if your product carries a…

Recycled nylon
Where nylon is chemically regenerated (depolymerised and repolymerised), it can be recycled repeatedly without loss of quality; this cannot be assumed for mechanically recycled grades, so ask the supplier which route was used. The…

Organic cotton
Certification fraud has been documented in this category at scale, mostly around transaction certificates. A scope certificate proves the supplier is certified; only an in-date transaction certificate for your own shipment proves the goods…

Recycled polyester (rPET)
Most of it is bottle-derived, which is a different argument from textile-to-textile recycling and is increasingly challenged for pulling feedstock out of a closed loop. Post-consumer or post-industrial is the question least often answered,…

Pineapple-leaf fibre
Plant content is higher than most sheet alternatives, but the resin layer decides wet performance and is the one suppliers describe least. Neither GOTS nor FSC applies to the finished sheet, whatever the marketing…

Coffee-ground leather
The least standardised category here: certification coverage is partial, bio-based percentages are rarely published, and there is little independent test data on file. If you specify it, budget for your own bench testing rather…

Mycelium leather
Hand and drape are the closest of any alternative to fine leather; supply is the constraint that decides the project. The best-known programme stopped in 2023 for want of capital, stranding the products designed…
